history

Project history and usage

fish-lsp is a Language Server Protocol implementation for the fish shell language, bringing editor features such as completions, hover, goto definition, formatting, diagnostics, rename, symbols, semantic tokens, and inlay hints to fish scripts.

Project history

The project was created in 2022 as the fish ecosystem was increasingly used for larger personal shell configurations and scripts. Its README positions the server as an editor-agnostic way to give fish users a consistent development environment rather than depending on each editor's local fish support.

Adoption history

fish-lsp is packaged for multiple developer workflows: the official README documents npm, yarn, pnpm, Nix, Homebrew, conda, mamba, standalone GitHub release binaries, and source builds. It also links client configuration examples and nvim-lspconfig integration, which is a strong signal that adoption is editor-driven.

How it is used

A normal setup installs the `fish-lsp` binary, configures an editor language client to run `fish-lsp start` for fish files, and optionally installs shell completions with `fish-lsp complete > ~/.config/fish/completions/fish-lsp.fish`.

Why package nerds care

For package nerds, fish-lsp is notable because it turns fish from an interactive shell with nice built-ins into a language that participates in the modern LSP/editor tooling stack. It also has unusually broad distribution paths for a young shell-specific tool.

Timeline
